Description

Aerosol generating device and aerosol generating system

The present invention relates to an aerosol generating device. In particular, the invention relates to an aerosol-generating device suitable for use with one or more consumables, especially different types of consumables.

Aerosol-generating devices, so-called electronic cigarettes, are known to use liquid to be vaporized or tobacco material to be heated. In some devices, vaporization of the liquid is combined with heating the tobacco. In another device, two cartridges containing different liquids are provided for selective parallel vaporization of the different liquids.

There is a need for an aerosol generating device that provides the user with more possibilities or choices when using different consumables.

According to the present invention, an aerosol generating device is provided. The device includes a device housing including at least two receiving chambers for receiving and receiving consumables in each of the at least two receiving chambers.

In some embodiments, each receiving chamber of the at least two receiving chambers is connected to a heating element for heating the consumable contained in the respective receiving chamber, or to an external heating element of the consumable for heating the consumable contained in the respective receiving chamber. It may include either electrical contacts or an induction coil for heating susceptor material provided within the device or consumable.

The device may further include at least two mouthpieces, wherein each of the at least two mouthpieces covers a receiving opening of a receiving chamber of the at least two receiving chambers when mounted in the device housing.

The airflow into and out of each of the at least two mouthpieces may be kept separate from the airflow into and out of each of the other of the at least two mouthpieces.

With the use of this device, each receiving chamber is accessible through a separate mouthpiece. Accordingly, each consumable arranged in the receiving room is accessible through a separate mouthpiece. At least two, preferably different, consumables can be received within the device and then remain ready for use by the user without further preparation of the device. For example, if one of the consumables is selected for use, repositioning of the mouthpiece is not necessary. In particular, switching between different consumables is readily available, for example between subsequent puffs. Additionally, the different receiving chambers and each mouthpiece can be individually used only for certain types of consumables. Assigning one mouthpiece to one receiving chamber prevents contamination of the receiving chamber and each mouthpiece by material from consumables stored in other receiving chambers. This may also improve the smoking experience over longer periods of device use.

The aerosol-generating device provides the user with a choice as to which consumables contained in the containment chamber should be used subsequently or alternately and to what extent. The desired consumer experience may be voluntarily selected depending on the type of consumables provided within the receiving room. For example, one may voluntarily choose between a flavor-based experience or a nicotine-based experience.

Preferably, each of the at least two mouthpieces includes an inlet opening and an outlet opening. Each inlet opening is aligned with the receiving opening of one of the at least two receiving chambers. Each outlet opening is individually accessible to the user. Therefore, puffing from any mouthpiece is possible at any time. Depending on the consumables contained in the receiving chamber associated with each mouthpiece the user is puffing, a respective user experience is provided.

The mouthpiece may be a separate, independent device part. This allows each receiving compartment to be opened and closed individually, for example for removal or replacement of consumables.

The mouthpiece may form a mouthpiece unit. Accordingly, the at least two mouthpieces can be connected, for example integrated into an assembly of mouthpieces. For this reason, only one device part needs to be manufactured and assembled together with the device housing. Additionally, only one device component needs to be handled to access all of the device's compartments simultaneously.

The device may include a mouthpiece, which is all a separate device part. The device may include a mouthpiece and a mouthpiece unit, which are separate device parts. The device may include one or more mouthpiece units. For example, the device may include a mouthpiece unit, for example, comprising two connected mouthpieces and one or more individual mouthpieces. The device may comprise, for example, two mouthpiece units, each comprising two connected mouthpieces.

In some embodiments, at least two mouthpieces of the device can form a mouthpiece unit. Advantageously, the airflow into and out of each of the at least two mouthpieces of the mouthpiece unit can be kept separate for each of the at least two mouthpieces. Thereby, although the mouthpieces are assembled into one device component, the mixture of vaporized substances from two or more consumables may be kept separate.

Materials from the substrate contained in the consumable may be transported by an air stream passing through the substrate or an air stream passing through the consumable. These substances can be entrained simply by passing air currents. For example, airflow passing through a tobacco substrate may be entrained with tobacco flavor. Substances to be inhaled can also be actively generated, for example, by heating the substrate contained in the consumable and forming an inhalable aerosol. Other nebulization processes may also be used for aerosol generation.

In the device, preferably, at least one of the at least two consumables is heatable.

In the device, all consumables are heatable.

Advantageously, the substrate is heated in order to aerosolize the consumable or the substances contained therein. This can be done by heating the substrate via a heating element within the consumable or by providing a heating element within the device. If a heating element or other atomizing element is included in the consumable itself, the receiving chamber preferably has respective electrical contacts for connecting a power source within the device to the consumable to provide the required power to the atomizing elements within the consumable, such as a heater. It includes.

Heating of the consumables is preferably carried out resistively or inductively. A resistive heating element may be provided in the device or consumable.

One receiving chamber may contain a heating element and the other containing chamber may contain electrical contacts.

Both of the at least two receiving chambers may contain both a heating element and electrical contacts, for example for an external atomizing element. This provides many options for different consumables to be used with the aerosol-generating device according to the invention. This also makes the device easier to use by eliminating the need to ensure that the receiving chamber is adapted to a particular consumable or aerosolization option.

Heating elements within the device may be disposed within the walls of the receiving chamber. For example, a resistance-heated metal track may be placed within the walls of the containment chamber or a resistance-heated wire may be placed within the walls of the containment chamber. An inductor in the form of an induction coil may be disposed within the wall of the receiving room and may surround the consumables contained within the receiving room.

The heating element within the device may extend into the receiving chamber. For example, the heating element may be a resistively heated heater blade or an elongated susceptor. At least one of the receiving chambers may include a heating element extending into the receiving chamber.

A variety of consumables may be used or determined to be usable with the aerosol-generating device according to the present invention.

Examples of consumables include, for example, liquid-containing cartridge or tank systems with or without an integrated aerosolizing element, such as a cartomizer (combined cartridge and atomizer); solid substrates containing consumables, for example tobacco-containing plugs; Capsules containing a solid substrate (the solid substrate may be tobacco material, homogenized tobacco material in powder form or a substrate); vaporizing wax; and crimped or corrugated tobacco sheets.

The receiving chamber can accommodate different types of consumables, for example liquid-containing cartridges, solid-based consumables, and preferably solid tobacco-based consumables.

Different consumables may have different shapes, for example diameters. Preferably, the different consumables contain different aerosol-forming substrates, such as any one or combination of different tobacco materials, different flavors, different nicotine contents, different combinations of substances. Preferably, the different consumables comprise different ways in which they are heated or generally comprise different ways in which the material of the consumables is atomized. Different consumables may include both different aerosol-forming substrates and different substrate spray regimes.

The receiving chamber may also contain consumables of the same type, for example liquid-containing cartridges. Preferably, the cartridges then contain different liquids, for example with different flavors or different substance combinations.

Consumables may use different methods to release inhalable substances from the consumable. For example, when one consumable in one chamber contains a heated liquid, the other consumables in another chamber may be an unheated tobacco substrate or may be unheated but alternatively contain a sprayable substrate.
